We construct a dyon solution for the noncommutative version of the Yang-Mills-Higgs model with a 𝜗-term. Extending the Noether method to the case of a noncommutative gauge theory, we analyze the effect of CP violation induced both by the 𝜗-term and by noncommutativity proving that the Witten effect formula for the dyon charge remains the same as in ordinary space.
